The Mr. Robot Cast Had a Bunch of Recognizable Guest Stars You May Know

The Mr. Robot cast had a lot of people from other popular projects. Of course, that includes Alf!

By Joe Dziemianowicz

With its intriguing blend of suspense and psychological drama, Mr. Robot is one well-oiled TV machine. 

From 2015 to 2019, the USA Network series starred Bohemian Rhapsody Oscar champ, Rami Malek, in his Emmy-winning role as Elliot Alderson, a brilliant but troubled cybersecurity ace. 

Elliot is recruited by the mysterious anarchist “Mr. Robot,” played by Christian Slater, to join a group of hackers — Fsociety — aiming to bring down corrupt corporations. What could go wrong? Well, several twists and turns later, the exciting series came to a close after four seasons

Elliot’s shaky grip on reality is apt to make you wonder what’s actually going on at times. What’s constantly clear is that Mr. Robot is jammed with juicy characters, including ones played by series regulars as well as ones who popped in for relatively short stays. 

With Mr. Robot now on streaming, it’s a great time to check out the best guest stars across the show's four seasons, in our spoiler-free roundup.
